Descriptive and Inferential Statistics - 955 Words

Descriptive and Inferential Statistics Statistical methods in psychology have two main branches, which are descriptive and inferential. They each play a major part in the data that is collected for research and other studies. This paper will show the functions of statistics, how descriptive and inferential statistics are defined and the relationship between the two. Statistics is a necessary tool in psychology. It provides data for research studies as well as providing background information and support. Without it, understanding the various aspects of psychology and what causes disorders and behaviors would be almost impossible. Scientific, social, and economic studies use statistics in one form or another (Anand, 2013). These†¦show more content†¦Also known as the average, the mean is gathered by adding all the scores in the number series and dividing it by the amount of numbers in the series (Boeree, 2005). Unlike descriptive statistics, inferential statistics is used to make inferences about a large population based on a sample group. A sample refers to a group that is a subset of a larger group. The inferences of the sample group are not exactly error proof; it does not represent the larger population 100%. In psychology, there are different types of inferential statistics that are used. Depending on the type of variable being measured, the inferential is used. Variables measured by an inferential such as nominal, ordinal, and interval and ratio are compared to one another to determine the correlation from one another (McHugh, 2003). Methods such as descriptive and inferential statistics are used to better understand sums that can be produced when conducting research. Psychologists today give the world and its people a better understanding of the environment present by using these methods. Numbers can represent a small or large group of people depending on the set up of the statistical formula. Once place within a method, numbers become a visual aid for research and puts into perspective a once large sum. References Anand, A. (2013, May 7). 7 Most Essential Functions of Statistics.
